Screws for coupler boxes

[Jgladmon]

This is my first post, so I hope I'm doing this right.

I'm trying to find what size and/or where I can buy the coupler box screws that are on the Bachmann Spectrum Heavyweight Passenger cars, like Item No. 89343.  The Parts List that came with the coach says the screws are Stock No. 6610.  I've had no luck searching for that number to get what size these screws are to buy them somewhere.  I have compared them to some others I have, and I can say with certainty that these #6610 screws are smaller in diameter than 2-56 x 1/8 screws, but appear to be the same length. 

Can anyone help me?

It may be a M1.6 x .35 x 3mm metric screw. If you can't find one at a local hardware or home improvement center, Micro-Fasteners is a good source for small screws.
